Realtek wrongly detect rear audio output

526 Views 28 Replies 3 Participants Last post by  zvone
New desktop, everything OK except speakers sound. There is only front audio 3.5 output for speakers or headphones. Speakers (Logitech Z313) are connected but sound is horrible because headphones are enabled by default as a playback device. Under device manager my Acer monitor (no speakers) is listed as a HD audio display!? Realtek Audio Console shows that speakers are connected to the rear 3.5 output which doesn't exist (see the screenshot). I tried literally everything (updating and uninstalling drivers, restarting in safe and offline mode, downloading all Realtek compatible software...). The one thing that worked was Microsoft HD audio driver 10.0.22621.608 but only offline. As soon as I connect to the net headphones are automatically back as a default. Any advice is more than welcome.

My desktop PC is connected to modem only via ethernet cable. I disabled WI-FI connection. But that's not important. Browser has nothing to do with speakers. I managed to get Intel driver working when ethernet cable was out. As soon as I put it back Realtek driver took over as a default. I'll send serial number as soon as I get home but there's nothing I can do with Lenovo support. The latest driver is installed and speakers don't work, so I'm stuck. Because it's a most likely faulty software I can't even return PC to the store.

Only speakers got analog jack !? Impossible. They are 2.1. channel (2 speakers & subwoofer) and sound was perfect on my old PC.

From this screen, under the Advanced tab, does the test work OK?

Also, as Peter requested, what is the model # of that system?

No it doesn't work but it's gone for good. I just returned it to the store. Thanks for your help.

I tried that as well but it didn't work. This morning HD video become blurry as well and some strange noise (humming) was coming from the case. Tried to restart PC and then everything died. Windows couldn't boot and was unable to repair itself. Factory reset also didn't work so the only option left was to install it from USB or CD (which I didn't have). Luckily I was able to return it to the store, swap it for the only regular size desktop in whole city of Adelaide + got $100 back because it was cheaper. Hopefully this one won't give me any headache (it's still in the box). Once again, thanks for your time & help I really appreciate it. Azure Font Aqua Electric blue Technology
